The heart, I suppose, is like a muscle. When there is an ache in the shoulder, the neck, behind the shoulder blade, running downward, a headstand does the trick, even if it might seem that rest would be the best thing. And so the heart, to align itself and work properly, requires of us to be the city of light, the candle, to turn the other cheek and all the things the Sermon, or Buddha, lays out for us. "Oh, shit, really?" Yes, the pain is only the point halfway.
